|One ounce silver rounds.|
Purchased in Richmond, CA early 1990s for use in castings. Dan Lewis, a coin dealer, tells me that these are called "silver rounds" because they are round but are not actually coins issued by any government. He reports they are the part of the numismatic world known as exonumia.
I've cast a dozen or so little things out of silver over the years. It's not as expensive as you might think. See zinc for a long story about metal casting.
